3.4 Configure Pool

To configure an Office Communications Server Enterprise pool

1. Log on to the computer with an account that is a member of the RTCUniversalServerAdmins group.

2. Insert the Microsoft Office Communications Server CD. The deployment tool will start automatically. If you are installing from a network share, go to the \Setup\I386 folder, and then double-click setup.exe.

3. In the deployment tool, do one of the following:

   • Click Deploy Pools in a Consolidated Topology.

   • Click Deploy Pools in an Expanded Topology.

4. At Configure Pool, click Run.

5. On the Welcome to the Configure Pool/Server Wizard page, click Next.

6. Before you can continue, the Office Communications Server administration tools must be installed if they are not already on the computer. On the Administrative Tools required page, click Next to install the administrative tools.

7. On the Server or Pool to Configure page, select the pool from the list, and then click Next.

8. On the Load Balancer Configuration Parameters page, do one of the following:

   • If you are using a load balancer that is configured to perform DNAT (destination network address translation), click Load balancer is configured in DNAT (destination network address translation) mode.

   • If you are using a load balancer that is configured to perform SNAT (source network address translation) or if you are not using a load balancer, click Load balancer is configured in SNAT (source network address translation) mode.

     Note

     Using a load balancer in SNAT mode is recommended for ease of deployment, however be aware each SNAT IP address on the load balancer limits the maximum number of simultaneous connections to 65,000.
     If you deploy load balancer in SNAT mode, ensure you configure a minimum of one SNAT IP address for each group of 65,000 users. (The open number of connections generally corresponds to the number of active users.) For example, in a deployment supporting 100,000 users, you would configure two SNAT IP addresses.

9. On the SIP domains page, verify that your SIP domain appears in the list. If it does not, click the SIP domains in your environment box, type your SIP domain, and then click Add. Repeat these steps for all other SIP domains that the Enterprise pool will support.

10. When you are finished, click Next.

11. On the Client Logon Settings page, do one of the following:

    • If the Office Communicator clients and Microsoft Office Live Meeting 2007 clients in your organization will use DNS SRV records for automatic logon, click Some or all clients will use DNS SRV records for automatic logon.

      If this server or pool will also be used to authenticate and redirect requests for automatic sign-in, then select the Use this server or pool to authenticate and redirect automatic client logon requests check box. When you configure automatic client logon, you must designate one (and only one) Enterprise pool or Standard Edition Server to authenticate and redirect client sign-in requests.

    • If the Office Communicator clients and Live Meeting 2007 clients in your organization will not be configured to use automatic discovery, click Clients will be manually configured for logon.

12. When you are finished, click Next.

13. Select from the following:

    • If, in the previous step, you selected Clients will be manually configured for logon, skip to the next step.

    • If in the previous step, you selected Some or all clients will use DNS SRV records for automatic logon, on the SIP Domains for Automatic Logon page, select the check box for the domains that will be supported by the server for automatic sign-in, and then click Next.

14. On the External User Access Configuration page, do one of the following:

    • If you have deployed your edge servers and configured all necessary settings as described in the Microsoft Office Communications Server 2007 Edge Server Deployment Guide, click Configure for external user access now. Refer to the edge server document for details on completing this wizard.

    • If you have not deployed any edge servers, click Do not configure for external user access now.

15. When you are finished, click Next.

16. Do one of the following:

    • If, in the previous step, you selected Configure for external user access now, refer to the Microsoft Office Communications Server 2007 Edge Server Deployment Guide for details on completing the wizard.

    • If, in the previous step, you selected Do not configure for external user access now, skip to the next step.

17. On the Ready to Configure Server or Pool page, review the settings that you specified and then click Next to configure the pool.

18. When the files have been installed and the wizard has completed, verify that the View the log when you click Finish check box is selected, and then click Finish.

19. In the log file, verify that <Success> appears under the Execution Result column. Look for <Success> Execution Result at the end of each task to verify that pool configuration completed successfully.

20. Close the log window when you finish.

Additional SIP server, domain, and forest settings can be configured using the instructions in the Microsoft Office Communications Server 2007 Administration Guide, Microsoft Office Communications Server Administration Guide, Microsoft Office Communications Server 2007 Archiving and CDR Server Deployment Guide or the Microsoft Office Communications Server 2007 Edge Server Deployment Guide. For details about configuring SIP user settings, see 6.3 Configure Users later in this document.
